GE IS210AEDBH4AGD
Overview
The IS210AEDBH4AGD is a critical component within GE’s Mark VIe Speedtronic turbine control system. It is an Analog Excitation Device (AED) board, specifically designed for gas or steam turbine control applications. Its primary function is to interface with the turbine’s excitation system, handling both analog input signals (like field voltage and current feedback) and analog output signals (to control the exciter field).
This board is part of the Mark VIe Distributed I/O Package, meaning it resides in an I/O pack (e.g., an EX2100e Excitation Control pack) and communicates with the central controller (e.g., a UR controller) over the high-speed PDH (Peer-to-Peer Data Highway) network.
Detailed Technical Parameters

| Series/Platform | Mark VIe Speedtronic Turbine Control System |
| Board Type | Analog Excitation Device (AED) |
| Part Number | IS210AEDBH4AGD |
| Functional Role | Interfaces between the Mark VIe controller and the turbine’s excitation system. Provides analog input and output channels for excitation control and monitoring. |
| Input Channels | 6 Analog Inputs: • Typically used for: – Field Voltage Feedback (1x, isolated) – Field Current Feedback (1x, isolated) – Var/Power Factor Transducer (1x) – Line Voltage Transducer (1x) – Manual Voltage Adjust (1x) – Spare (1x) • Input Range: Configurable, typically ±10 VDC or 4-20 mA. |
| Output Channels | 2 Analog Outputs: • Typically used for: – Exciter Field Control (1x, ±10 VDC or 4-20 mA) – Spare/Secondary Output (1x) |
| Communication | PDH (Peer-to-Peer Data Highway): • Connects to other boards in the I/O pack (like the controller board, IS210AEPCH1B) via a high-speed backplane. • Communicates with the central turbine controller (e.g., Mark VIe UR) over the PDH network. |
| Key Features | • Isolation: Provides electrical isolation on critical field feedback inputs for noise immunity and safety. • LED Indicators: Status LEDs for power, communication, and fault diagnosis. • Software Configurable: All input and output ranges, scaling, and functionality are configured within the ToolboxST application. |
| Compatibility | • Designed for use in EX2100e excitation control systems. • Fits into a VME-style I/O pack chassis (e.g., IS200VPROH1B). • Works in conjunction with other Mark VIe boards like the IS210AEPCH1B (PDH Controller). |
| Power Requirements | Receives power from the backplane of the I/O pack. Typical voltage: +5 VDC and ±15 VDC. |
| Environmental Rating | Designed for industrial control environments. Typically rated for operation in temperatures from 0 to 60°C (32 to 140°F). |
Functional Description
The AEDB board acts as the “translator” between the digital world of the Mark VIe controller and the analog world of the excitation system.
- Inputs: It receives analog signals from transducers on the generator (e.g., field voltage, field current). It converts these analog signals into digital values and transmits them over the PDH network to the controller.
- Processing: The central controller runs the excitation control algorithms (e.g., automatic voltage regulator – AVR).
- Outputs: Based on the control algorithm, the controller sends a digital command back to the AEDB board. The board then converts this command into an analog output signal (e.g., ±10 VDC) that is sent to the power amplifier to control the strength of the exciter field, and ultimately, the main generator’s output voltage.
